Algebra.Com's Answer #198309 by unlockmath(1688)![]() ![]() You can put this solution on YOUR website! Hello, \n" ); document.write( "We can set up two equations and solve the problem. \n" ); document.write( "Let x be Crocus and y be daffodil. So: \n" ); document.write( "x+y=40 \n" ); document.write( ".45x+.65y=20.40 \n" ); document.write( "Multiply the first equation by -.45 so to eliminate x. So we get: \n" ); document.write( "-.45x-.45y=-18 Now add this to the second equation: \n" ); document.write( "+.45x+.65y=20.40 \n" ); document.write( "And we get: \n" ); document.write( ".20y=2.40 Divide each side by .25 to get: \n" ); document.write( "y=12 Now we can find x by plugging 12 for y in the first equation: \n" ); document.write( "x+12=40 Subtract 12 from both sides to get: \n" ); document.write( "x=28 \n" ); document.write( "So now we know there are 12 daffodil and 28 crocus. \n" ); document.write( "RJ \n" ); document.write( "Check out a book that might help: \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
